What is the area of a circle with a diameter of eight

16 pi or approximately 50.24

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

r = d/2 where d is the diameter

r = 8/2 = 4

So plugging into the equation for the area

A = pi (4) ^2

A = 16pi

Using 3.14 as an approximation for pi

A = 16*3.14 = 50.24
